Ever-increasing core counts create the need to develop parallel algorithms that avoid closely-coupled execution across all cores. In this paper we present performance analysis of several par-allel asynchronous implementations of Jacobi’s method for solving systems of linear equations, using MPI, SHMEM and OpenMP. In particu-lar we have solved systems of over 4 billion un-knowns using up to 32,768 processes on a Cray XE6 supercomputer. We show that the pre-cise implementation details of asynchronous al-gorithms can strongly affect the resulting perfor-mance and convergence behaviour of our solvers in unexpected ways. 1
